How could I get the number of items in a dynamic list with Sass?

问题

<ul>
  <li></li>
  <li></li>
  <li></li>
  ...
  <li></li>
</ul>

Is it possible to get the 'n' value o the last item of a dinamic list with Sass? Like counting the number of items within the 'ul' using the @each or @for statements ?

回答1:

No. Sass only compiles to CSS. It is never sent to the browser. It has no knowledge of the DOM.
